This is where I disagree. Many of the Council Fathers were modernists, themselves, and they got what they intended.
Bugnini had the full support of Pope John XXIII to push his agenda through.
From the Liturgical Time Bombs of VC II:
The Bugnini schema was accepted by a plenary session of the Liturgical Preparatory Commission in a vote taken on January 13, 1962. But the President of the Commission, the eighty-year old Cardinal Gaetano Cicognani, had the foresight to realize the dangers implicit in certain passages. Father Gy writes: "The program of reform was so vast that it caused the president, Cardinal Gaetano Cicognani, to hesitate." [Flannery, p. 23.] Unless the Cardinal could be persuaded to sign the schema, it would be blocked. It could not go through without his signature, even though it had been approved by a majority of the Commission. Father Bugnini needed to act. He arranged for immediate approaches to be made to Pope John, who agreed to intervene. He called for Cardinal Amleto Cicognani, his Secretary of State and the younger brother of the President of the Preparatory Commission, and told him to visit his brother and not return until the schema had been signed. The Cardinal complied:
Later a peritus of the Liturgical Preparatory Commission stated that the old Cardinal was almost in tears as he waved the document in the air and said: "They want me to sign this but I don't know if I want to." Then he laid the document on his desk, picked up a pen, and signed it. Four days later he died. [Fr. Ralph M. Wiltgen, S.V.D., The Rhine Flows into the Tiber: A History of Vatican II (1967, rpt. Rockford, IL. TAN, 1985), p. 141.]
Exactly.
It's a question of degree. If the majority were modernists, why would the modernist mutineers have found it necessary to resort to embedding ambiguities in the documents?
